Studying translation in the ecological context enriches the study scope of translation studies. Based on the theory of eco-translatology and its engendering factors, this article expounds the three ecological dimensions in translation studies－the species, gender and race and reveals that in translation there exists the distinction between subjectivity and non-subjectivity and that between the centralized and the marginalized. Being essentially anthropocentric, androcentric and ethnocentric, these distinctions hamper dialogues between subjects. Through highlighting the difference consciousness in translation studies, the ecological perspective constructs the ecological translation theory, deconstructs the various centrisms and maintains the ecological balance of the interior system of translation studies.
